3. When fuel of different grades is stored in two tanks, if the ambient temperature
is lower than 0 degree and the fuel is easy to wax, it is necessary to fill the fuel pipe-
line with high-grade fuel before flaring in order to avoid the problem that the engine
cannot be started after long-term flaring.
CAUTION:
The auxiliary tank is filled with high grade fuel oil which can withstand
low temperature.
Operation method
1. 3 minutes before the vehicle shuts off, the vehicle stops, the user gets off and
rotates the handle to the mark of "auxiliary fuel tank" to fill the fuel pipeline with high-
grade fuel and prevent wax.
2. Before starting the vehicle, check that the switch handle is at the mark of "aux-
iliary fuel tank". If so, it can be started normally. If not, rotate the handle to the "fuel
tank" mark
3. Since there is no fuel heating device in the main fuel tank, users should judge
by themselves whether the fuel in the main fuel tank is waxed and whether the waxing
degree meets the normal operation of the vehicle. The user decides whether to switch
to no. 0 fuel in the main tank according to the judgment.
CAUTION:
1. The valve body of this product is strictly forbidden to be removed;
2. After the conversion from the main oil tank to the auxiliary oil tank, the
interval shall be more than 3 seconds, and then from the auxiliary oil
tank to the main oil tank. The continuous conversion operation shall not
be longer than 10 minutes;
3. In low temperature weather, in order to prevent the switch and the
pipeline from freezing and being unable to start the fire, please switch
the oil line to low-temperature oil before getting off the bus, so that the
oil line and the switch are filled with low-temperature oil;
